Given numbers are 645, 528, 270, 365
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 528) = 113520
GCD(645, 528) = ( 645 x 528 ) / 113520
= 645 / 528
= 645
Step2:
LCM(3, 270) = 270
GCD(3, 270) = ( 3 x 270 ) / 270
= 3 / 270
= 3
Step3:
LCM(3, 365) = 1095
GCD(3, 365) = ( 3 x 365 ) / 1095
= 3 / 365
= 3
So, Greatest Common Divisor of 645, 528, 270, 365 is 1
